INVALID-BE'DSTEAD.

LFECFI'LCATION forming part of Letters Patent No. 335,218, dated February 2, 1886.

A pplicalion filed November 1l, 1885. Serial No. 1&2.79(i. (No model.)

To all whom, it may concern,.-

Be it known that we, LUTHER XV. FILLE- BROWN, of Piqua, Miami county, Ohio, and FRANK B. CHANDLER, of Wayne, in the county of Kennebec and State of Maine, have invented certain new and useful Improvements in Invalid-Bedsteads; and we do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to theletters of reference marked thereon, which form a part of this specification, in which- Figure l is a plan view ofa bed-frame having our invention attached. Fig. 2 is a vertical longitudinal section of the same on line x x of Fig. l. Fig. 3 is a transverse section, on line yy, of the same. Fig. 4 is a detail transverse section on line z z of Fig. l, showing the arrangement of the gearing; and Fig. 2O 5 isa detail section of the ratchet-and-pawl mechanism.

The invention is an improvementin invalid bedsteads; and it consists in the construction and novel arrangement of parts, hereinafter described, and pointed out in the appended claims.

Referring to the accompanying drawings by letter, A designates the bed-frame, upon the inner surface of the side rails, B B, of which are bolted the transversely-opposite journal-- plates b b', respectively, having the bearings b2 b3, as shown in Fig. l.

C is a transverse hollow shaft having the journal c, which rests and turns in the bearings Z)z of the plate b, and C is a shaft which has its inner end inserted and turningfreely in the bore of the shaft (l, and provided on its outer end with the `journal c', which turns in the bearing Z)3 of the journal-plate b. The 4o shaft C extends to about the central longitudinal line of the bed-frame, and has the setscrew ci, passing through a threaded opening near its inner end and securing the two shafts -together,when desired, so that they will turn as one.

D is a transverse bar having the outer ends of the curved arms or bars D secured to its under surface, as shown in Fig. 2. The bar D is secured to the under surface of the mattress 5o by any desirable means, one method being shown in Fig. 2. The inner orlower ends of said bars are pivoted to the crank-arms E, each of which has a hub, e. There may be one or more crank-arms on each of the shaft-s O and C, the bore of said hubs heilig o1' proper size to lit well over and turn easily on the shaft upon which they are hung.

e e are set-screws, by means of which the crank-arms may be so secured to their shafts as to turn therewith.

F is a gear-wheel on the outer end of the shaft G, inside of the bearing of the same and gearing with the pinion F', the shaftfofwhich turns in bearings in the side rail, B', and in the arm of the bracketf, secured to the inner surface of said rail. The outer end of the shaftf passes through the side rail, B', and is squared to receive the crankhandl`e G, or a wrench.

H is a ratchet-wheel on the shaft f, outside of the pinion F and adjacent to the side rail, H. The said ratchetwheel is commanded by the pawl h, pivotcd on the inner side of said rail. h is a rod depending from said pawl and drawing the same down by gravity. pawl may be lifted by means of said rod when it is desired to lower the mattress.

Then the attachment is secured, either to the head or-loot ol the bed-frame, the setscrew al may be turned so as to make the shafts O C turn together. In that case the bar D is made in one piece, and there is only one crank-arm E secured on each of the shafts. This arrangen'ient is especially adapted for single beds. In double beds there are two crank-arms E on each of the shafts C C. Two mattresses of equal. size are placed on the bed-frame and the bar D is replaced by two bars of equal length, one secured to eachmattress, their meeting ends being over the central longitudinal line ol' the frame, as shown by the dotted lines g/ yof Fig. l.. One ol' the hars is secured to the crank-arms ofthe shaft C, and the other to the similar arms ol' the shaft C. rlwo persons can then recline on the bed, and each can have his position changed, independently of the other, in the following manner: Unloose the set-screws e of the shaft G, and tighten those of the shaft C, securing` the shafts together by the setscrew c2.' Then by turning the crank-handle G the crank-arms and attached bar D, con- The 7 IOO nected with the shaft C, will be raised,while the shaft C will turn in its crank-arms and not raise the saine. By unloosing the setscreW c2 the shaft C may be turned independently of the shaft C, so as to raise the adjacent mattress.

The shaft C enters the bore of the shaft G, and the set-screw ct may engage any part of the shaft G', so that the device may have its length extended or shortened and be applicable to bed-'frames of varying Width.

Having described ourinvention, We claiml. The combination of the bedframe, the j ournal-plates secured to the inner surface of the side rails thereof, the shafts C C', having their journals in the bearings of said plates, the adjustable crank-arms connected with said shafts, the rail D, secured to the under surface of the mattress, the connecting-arms
